Yea, I was speaking my magnetic stirrer. On top stirrer would be great to purchase. But thanks! If I do this some wonderful day, I will stirr it "medium"... I have to say, within a year, I have laser thermometer, digital screen in my new stirrer with temp. and stirr speed screens. And 0.0001 diamond scale, plus many many more. First I have to figure out, how simple Leuckart reaction can go wrong with just P2P and formamide. I'm so frustrated.
niesamowity filmik! Szacun dla twórców! w związku z tym mam pytanie do szanownej społeczności, faktem jest, że dokładnie zastosowałam się do instrukcji z niego, a na samym końcu, gdy doprowadziłam pH = 6, i wstawiłam naczynie do zamrażarki, po prawie 2 dniach wyjęłam je i zobaczyłam, że prawie nic się w nim nie utworzyło, poza garstką kryształków, które po przemyciu odwodnionym acetonem zniknęły bez śladu. o co chodzi? co dokładnie zrobiłam źle?
How much are you the best on your first what was the quality of Europe product is refusalization there was it looks where you curious would you suggest hirinmean mean I want to take all the precautions one last question was the final a quality would end up with a whole bunch of low quality bunk that I spent an arm and a leg for
@NinjaFlakkaZombie Well because Chinese vendors advertise it at prices so low that it's impossible to look away. They no longer offer it for sale in the open forum but if you pm them, they offered it to me for about $125/kg (2-bromo-4-methyl-1-phenylpentan-1-one) and $115/L for the pyrovelarophenone equivalent. I wouldn't accept anything illegal from China. The risk is astronomical in my opinion. I have bought it off of a major online marketplace, received it, sent from inside the USA, with no fanfare, no questions were asked and it's been 2 months and is long gone from my possession. It was expensive compared to Chinese prices. Basically $4/g.
The person is either licensed to receive such things ( the DEA does issue paperwork for businesses to have things of the nature), in a position to procure them with little risk ( such as the faculty of a University department licensed to possess it)or has put a lot of effert into obscuring his identity through incorporations business licensing and mail forwarding
